A control circuit of a bulletproof helmet automatic laying machine

Abstract

The invention discloses a control circuit of a bulletproof helmet full-automatic surface preparation machine. The control circuit comprises a programmable logic controller U1, a switch power supply U3, a stepper motor driver U2, a stepper motor M, a photoelectric switch SQ6, a magnetic induction switch SQ7, magnetic induction switches from SQ10 to SQ17, magnetic induction switches from SQ20 to SQ24, a start switch SB0, a stop switch SB1, an emergency stop switch SB2, a reset switch SB3, a manual / automatic change-over switch SB4, a manual stepper switch SB5, relays from J4 to J7, relays from J10 to J13, relays from J14 to J17, relays from J20 to J27, diodes from D1 to D20, indication lamps L1 and L2, an alarm HA and electromagnetic valves from HV1 to HV12. The control circuit has the advantages that automation command and coordination are realized in the whole work process; labor is reduced; and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bulletproof helmet fabric laying, and relates to a control circuit of a bulletproof helmet automatic laying machine. Background technique [0002] At present, the production of bulletproof helmets for soldiers in our country consists of multiple large sheets and multiple small sheets. The large and small sheets are made of dipped aramid cloth and cut according to the ruler. There are four cutting seams. During the production process, 4 large sheets are laid one by one, and then 1 small sheet is laid. The laying process is all manual laying, which requires a lot of labor, and such manual laying cannot guarantee every Accurate intervals and fixed angles between the individual pieces prevent the joints from spreading out evenly, making the laid pieces uneven, resulting in uneven laying, resulting in inconsistent thickness of each point on the finished helmet, and making the helmet bulletproof. Inconsistenci...
